Macro ensure_any

macro_rules! ensure_any {
    ($cond:expr, $($tt:tt)*) => { ... };
}

Ensures a condition, otherwise returns an AnyError.

This macro takes an expression as its first argument. If the expression evaluates to false, the macro expands to returning an error result. The error will be constructed by passing the remaining arguments after the expression to anyerr. See its docs for supported forms.
